我正在尝试的是获得我当前的位置（坐标），并且我想在网站上发布这些坐标。我已经使用 WAMP 制作了一个服务器。我已经编写了 php 代码和 java 中的代码。没有错误但没有数据发布在网站上
PHP代码
<?php
echo 'Hello, world!';
$json = $_GET['jsonpost'];//get the post you sent...
$data = json_decode($json); //decode the json formatted string...
print_r($data);
$id = $data->id;
$devid = $data->devid;
$latitude = $data->latitude;
$longitude = $data->longitude;
$service = $data->service;
$con = mysql_connect("","","");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("a5234826_ul", $con);
$devid = $_POST['devid'];
$latitude = $_POST['latitude'];
$longitude = $_POST['longitude'];
echo "devid" +$devid;
echo "latitude" + $latitude;
echo "longitude" + $longitude;
$sql = "INSERT INTO `a5234826_ul`.`locations` (
`id` ,
`devid` ,
`latitude` ,
`longitude` ,
`service`
)
VALUES (
NULL , '$devid', '$latitude', '$longitude', '$service'
)";
if (!mysql_query($sql,$con))
{
die('Error: ' . mysql_error());
}
mysql_close($con);
echo json_encode($variable);
?>
